Cristiano Ronaldo did not register a single shot on target in Real Madrid's 1-0 defeat at Athletic Club on Saturday.
Opta stats show the Portuguese has now failed to register an attempt on target in four of his last eight Liga fixtures, having previously managed at least one between the posts in every previous Primera Division appearance this term.
Ronaldo has hit seven goals in 12 games for Madrid in 2015, which is well below his usual goal-a-game ratio for the Spanish side, while Karim Benzema has five in 14 this year and Gareth Bale just three goals in as many matches as the trio struggle to replicate their 2014 form.
In midfield, meanwhile, Toni Kroos misplaced nine passes against Athletic, more than he has done in any other match for Real in all competitions since signing from Bayern Munich in the summer.
And it was another slow start for Carlo Ancelotti's side, who have gone in ahead at the break in just one of their last five Liga games - the 1-0 victory over Deportivo La Coruna at the Bernabeu last month.
Madrid have now lost four of their 14 fixtures in all competitions in 2015 and three out of 11 in La Liga so far this year.
